SPECIFICATION forming part of Letters Patent No. 285,718, datedE'eptember 25, 1883.

Application filed May 2, 1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. WILLA RD, of Chicago, in the county ofCook and State of Illinois, have invented certain new and use- 5 fulImprovements in Helves of Power-Hammers, of which the following, inconnection with the accompanying drawings, is a specification.

In the drawings, Figure 1 is a side view of the helve. Fig. 2 is abottom View of the same. Fig. 3 is a section in the plane of the line m;and Fig. 4 is a section in the plane.

of the line 3 showing the helveih position in the husk.

Like letters of reference indicate like parts.

The object of my invention is to make a durable helve for power-hammers;and to that end my invention consists of the means I employ for thatpurpose. 7

It also consists in certain other featnres of construction, all of whichwill hereinafter be referred to.

A represents the helve, which I make of two principal parts, a and a.The part a, I make of wrought-iron. In form the part a is tapering,gradually growing thicker toward its head I). In the under side of thehead I make a dovetail groove, c, adapted to receive a detachable die,having a rib adapted to enter the said groove. The head I) is made inone and the same part or piece with the part a. d d are shoulders orlugs, also made in one and the same part or piece with the part a, andare adapted and arranged to aid in retaining the husk in its properplace. The part a, I make of wood. This part I also make tapering, itbeing smallest at or near the head of the hammer, as shown, thus givingthe appearance of uniform thickness to the greater portion of the helve.

B B are clips or U-bolts, the threaded ends of which pass through thebars or plates 13 B; and O O are nuts upon the'projecting screwthreadedends of the said clips.

D D are bolts passing directly through the parts aand a, and d d arenuts on the ends of the said bolts. By this means the parts a and a areclamped or bound very tightly or firmly together, and may be arrangedtogether and detached from each other with facility.

E E are slabs of wood, which I arrange on the sides and bottom of thatpart of the helve to which the husk is applied; and F is the husk. InFigs. 1 and 2 I have not shown the husk, and only show it in Fig. 4 forthe purpose of illustrating the relative position of the slabs E E withrelation to the husk and helve. The husk may. be made in any suitable orwellknown way. M5

I find that a very strong and durable helve is produced by making thepart a of a long piece or bar of wrought-iron, and by clamping to it abar of wood of the same or of about the same length. The vibrationsproduced affect both the iron andthe wood when so com- .bined lessinjuriously than when the helve is made either all of iron or wholly ofwood, and this combination of the two long bars a and a, made of solidmaterial, consisting of iron and wood,respectively, when bound orclamped together to constitute the helves of hammers of this class,constitutes the principal feature of my invention. The lining of woodbetween the husk and the helve serves as a cushion, and also diminishesthe bad effects commonly result- 7 5 ing from the frequent vibrations orjars following the blows. Also, some of the other details ofconstruction now described, though not necessarily all employed in thesame hammer, may be used with advantage. I make both bars a and a ofabout the same length and of solidmaterial.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in the helve of a hammer of the class hereinreferred to, of the wrought-iron bar a, having a head made in one andthe same part therewith, and the wooden bar a, one arranged above theother, 0 substantially as and for the purposes specified- 2, Ahammer-helve consisting of the combination of the long taperingwrought-iron bar a, having a head made in one and the same parttherewith, and the tapering wooden bar a, clamped to the upper face orside of the bar a, substantially as and for the purposes specified. v

8. The combination, in the helve of a powerhammer, ofthe solid longwrought-iron bar a,

having a head made in one and the same part therewith, and the solid andlong wooden bar a, clamped to the upper side or face of the bar a,having a grooved head made in one and the a, substantially as and forthe purposes specisame piece therewith, and the Wooden bar a, fied.clamped to theupper side or face of the bar a,

4. The combination, in a power-hammer, of both constituting togetherthehelve of a power I 5 5 a Wroughtiron bar and head, both made in hammer,substantially as and for the purposes one piece a wooden bar arrangedabove the set forth. said wrought-iron bar and clamped thereto, and acushion or lining of wood arranged be- CHARLES VILLARD' tween the hclveor huslq substantially as and Vv'itnesses: 10 for the purposesspecified.
